Multiple answer question about membrane proteins

Recommended Posts

Q: Membrane proteins of mice cells were marked with green and membrane proteins of human were marked with red. The cells were fused together. What would be seen after 2 hours?


a) Red and green markers fully mixed

b) All red markers and no green markers

c) Half of the new cell with green markers and the other half with red

d) Red markers on the inside of the membrane and green markers on the outside


The answer was a. And I don't understand why. What principle is under this? It should be quite easy, but I still can't fathom it out.


Thank you in advance!

Proteins can move freely within the phospholipid bilayer, according to the fluid-mosaic model. 

So basically since they can move around, the green and red will fully mix.
